3. Waves in a lake are 6.0 m apart and pass a person on a raft every 2.0 s. What is the speed of the waves?

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Need in all of themmm only answer if you know pls
